Abstract:
Process wherein trimethylphenol is oxidised with oxygen or an oxygen-containing gas in the presence of a catalyst which contains a copper(II) halide in a two-phase reaction medium consisting of water and an aliphatic alcohol at high temperature, characterised in that the reaction is performed in a mixture of water and a saturated aliphatic alcohol with 12 to 18 C-atoms and a flash point above 120 DEG C, such as 1-dodecanol, 1-tetradecanol, 1-hexadecanol or 1-octadecanol, especially 1-dodecanol, and at temperatures between 60 and 100 DEG C. … Particularly good yields of TMBQ are obtained when the reaction is performed in the presence of a copper(II) halide, such as CuCl2 or CuBr2, and an alkaline earth metal halide, especially CaCl2 or MgCl2, or an alkali metal halide, especially LiCl and NaCl, as catalyst system.
